A wind cone helps pilots quickly identify wind direction and approximate velocity before takeoff, during approach, and while operating near the runway or landing area. Even when electronic weather systems are available, a visible wind cone gives pilots a direct, real-time view of what the wind is doing at the surface. There are two types of wind cone assemblies: L-806 and L-807 systems. Let’s explore key differences between these two wind cone configurations.

Why Wind Cone Size Matters for Airfield Safety
Wind cone size matters because pilots need to readily see and interpret wind conditions, often while managing several other tasks at the same time. A properly sized wind cone helps show where the wind is coming from and gives a basic sense of wind speed based on how far the cone extends. If the cone is too small or difficult to see from the runway, it might not provide the quick visual reference pilots need.
Under the Federal Aviation Administration (FAA) specifications, wind cone assemblies are classified into two configurations: L-806 and L-807. The L-806 model is designed for installation on low-mass support structures, whereas the L-807 model is intended for mounting on rigid support frames. While Size 1 wind cones are compatible with both L-806 and L-807 assemblies, Size 2 cones are restricted to L-807 systems.
Different airfield types require different wind cone configurations. A small private airstrip, heliport, or supplemental runway location might not need the same wind cone setup as a larger airport with more aircraft activity. In many cases, the L-806 system is suitable for smaller or supplemental use, while the L-807 system is often chosen when stronger visibility, a larger wind cone, or a more permanent installation is needed.
What an L-806 Wind Cone Is Used For
An L-806 wind cone is typically used for smaller airports, heliports, vertiports, and supplemental wind indicator locations. It is designed around a Size 1 wind cone, a practical choice for lower-traffic areas or limited operating spaces where pilots still need a clear surface wind reference. If you operate a smaller facility, an L-806 wind cone can provide pilots with wind direction and approximate velocity information without requiring the larger setup often used at bigger airfields.
Hali-Brite’s Wind Cone L-806, for example, is available in lighted, non-lighted, and solar-powered configurations, giving airfield operators flexibility based on power access, operating hours, and site layout. It offers 50,000 to 100,000 hours of lamp life. For airfields near the coast and other locations where salt air can shorten the lifespan of exposed equipment, Hali-Brite offers a marine-treated option, recommended to increase useful life in corrosive environments.
What an L-807 Wind Cone Is Used For
An L-807 wind cone is designed for broader airport applications and is often used where higher visibility is needed. Unlike the L-806, an L-807 wind cone can support either a Size 1 or Size 2 wind cone, depending on the airfield requirements. Size 2 is commonly used as a central wind indicator at larger airport locations. If your airfield has longer runways, more aircraft activity, or a layout where pilots need to see the wind cone from farther away, an L-807 wind cone is usually the better fit.
Hali-Brite’s Wind Cone L-807 is a system built for these wider airport needs. It is available in externally lighted, internally lighted, or unlighted options, allowing you to choose the setup that fits your operating environment. LED models can use 80% to 90% less power than halogen lamps, reducing energy demand over the life of the wind code system. Its nylon sock is treated for rot, mildew, and water repellency, helping the wind cone hold up better under outdoor airfield conditions.
Choosing the Right Wind Cone System for Your Airfield
Choosing between an L-806 wind cone and an L-807 wind cone comes down to how your airfield operates. A smaller airport, heliport, or lower-traffic location might only need a compact system that gives pilots a clear surface wind reference in a smaller operating area. In that case, an L-806 system can be a practical fit. For larger airfields, busier airport environments, or locations where pilots need better visibility from farther away, an L-807 wind cone might be the better option.
Consider lighting, power access, weather exposure, and maintenance needs. A lighted wind cone might be necessary if your airfield supports nighttime or low-visibility operations. A non-lighted system might be enough for daytime-only use. Solar-powered options can be helpful when electrical access is limited or when you want a more flexible installation. The right choice should support pilot safety, align with your site conditions, and help your airfield remain in compliance with FAA requirements.
Hali-Brite provides reliable, FAA-compliant airport lighting solutions built for different airport needs. We offer both L-806 and L-807 wind cone systems, lighted or non-lighted, along with solar-powered options to fit your airfield layout and operating environment. Our wind cones are designed for practical use, long-term performance, and clear visibility where pilots need it most.
